Completely nutty that it takes X2 watts in a mercury vapor bulb to produce the lumens that an X1 metal halide or X1 high pressure sodium lamp can produce.

And it does not take very long before it starts loosing these lumens. Metal halide is superior here, and it is not hard to understand the mercury bulb ban.

Made in Sweden

I’ve always been pro-mercury when it comes to streetlighting. Mainly because of the extremely long bulb life.

The mercury lamps that loses their brightness fast, uses thorium emitter, which blackens the arctube very fast. There are mercury lamps with emitter that turns the arctube white instead of black, and these lamps don't suffers from such high lumen depreciation: http://www.lamptech.co.uk/Spec%20Sheets/D%20MB%20Osram%20HQA125.htm
